In Ezra it is so amazing how you get to see Gods Faithfulness to His people. Here again He is giving the people of Israel Love. He had exiled them and now is bring them back again. Not because they deserve it , but because he is a God of his word He is a God of Love and compassion for His people.
In Nehemiah not only has he brought the people back , but He again is sending them the help they need ,by the way of Nehemiah. When God sends someone it is not to glorify that person , but to give others the opportunity to see how Great Our God is. Because Nehemiah was obedient to God , God was able to do a mighty work in the city that no one else was able to do. And because of that the people would turn back to Him.
